thumb|A 20 lb () steel propane cylinder. This cylinder is fitted with an overfill prevention device (OPD) valve, as evidenced by the trilobular handwheel. Propane () is a three-carbon chain alkane with the molecular formula . It is a gas at standard temperature and pressure, but becomes liquid when compressed for transportation and storage. A by-product of natural gas processing and petroleum refining, it is often a constituent of liquefied petroleum gas (LPG), which is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation; other constituent
Propane is a gas composed of three carbon atoms that can be liquefied under pressure, making it easier to store and transport for use as fuel. It is produced as a by-product of natural gas and oil processing, and is commonly used in homes and industries for heating, cooking, and powering vehicles.
